We report on numerical experiment of the recurrent onset of helical "blowout"jets in an emerging flux region (EFR). We find that these jets are running withvelocities of $\sim 100-250\,\mathrm{kms^{-1}}$ and they transfer a vast amountof heavy plasma into the outer solar atmosphere. During their emission, theyundergo an untwisting motion as a result of reconnection between the twistedemerging and the non-twisted pre-existing magnetic field in the solaratmosphere. For the first time in the context of blowout jets, we provide adirect evidence that their untwisting motion is associated with the propagationof torsional Alfv\'en waves in the corona.
